FIELD OF THE INVENTION

This invention relates to shoe inserts. More specifically, this invention relates to a shoe insert that protects a toe area of a foot and is removably coupled to an inner surface of a shoe upper.

BACKGROUND OF THE INVENTION

Construction workers, technicians, movers, landscapers, mechanics and other professionals in industrial, service and construction industries often work in hazardous settings. As such, falling or rolling objects, shreds of metal and other rigid construction materials pose a continuing threat of injury to the feet and toes of workers in these environments. Even non-professionals, such as the so-called “do-it-yourselfers”, are not always safe in the home, the woodshop, or the garage from falling objects.

To overcome such hazards, personal protective equipment is often used in many occupations. Safety shoes (also known as steel-toe boots, steel-capped boots or safety boots) having a steel toe box for protecting the wearer's toes are well known. Such shoes have a protective reinforcement in the toe, commonly combined with a sole plate, which protects the foot from falling objects and punctures from below. Traditionally made of steel—often the entire toe box and insole are reinforced with steel—the reinforcement can also be made of a composite material, or a plastic such as thermal polyurethane (TRU). Thus, safety shoes and boots protect the feet, help prevent injuries to them, and reduce the severity of injuries that do occur in the workplace.

According to the Occupational Safety and Health Administration (OSHA), safety shoes should be sturdy and have an impact resistant toe, and may be required in certain settings. However, workers often complain that safety shoes are uncomfortable, very expensive, and too bulky and heavy on their feet. Indeed, some individuals have foot problems that compel them to wear special shoes. Workers also complain that the safety shoes are not aesthetically pleasing and that the available styles are limited. As a result, many workers in hazardous occupations simply choose not wear safety shoes at all, which is serious safety violation that could lead to termination of employment and result in huge liability and fines in the way of tort suits and OSHA Recordable Accidents and Worker's Compensation Claims.

In today's economy, companies, especially those in the automotive and manufacturing industries, are looking for ways to cut costs, but at the same time, providing a safe working environment or employees. What is needed is a protective, comfortable, stylish and cost-effective insert that offers protection to the toes and the bottom of the foot.
